Title: Apparatus for detecting multiple cyclic permutable code
Inventor: CHOI SEONG NAM
IPC: H04J3/00
Filed: 1998-12-26
Abstract: PURPOSE: A multiple cyclic permutational code detecting apparatus is provided to be able to detect a plurality of channel cyclic permutational codes only by a single cyclic permutational code detecting apparatus by time dividing the plurality of channel cyclic permutational codes. CONSTITUTION: A multiple cyclic permutational code detecting apparatus comprises a time division cyclic permutational code(CPC) decoding part(200), a control clock generating part(227), a multiplexer(229), a CPC detecting part(300), and a CPC division part(400). The time division CPC decoding part(200) gets a time division subscriber information channel data according plural channels, and serially decodes the time division data into an original reception speed according to each channel. The control clock generating part(227) generates a control clock indicating a time division point of time and a decoding point of time of the time division CPC decoding part(200). The multiplexer(229) multiplexes the decoded CPC from the time division CPC decoding part(200). The CPC detecting part(300) compares a previous multiplexed CPC with a next multiplexed CPC. The CPC detecting part(300) recognizes the multiplexed CPC as a valid CPC when the CPCs are identical and when the same CPC is cycled by a predetermined frequency. The CPC division part(400) latches the valid CPC according to each channel, and generates a valid signal when the valid CPC is detected in the CPC detecting part(300).

Filed: 1998-12-29
Abstract: PURPOSE: In a plating process of a lead frame, a drain pipe connection structure of plating baths is provided to enhance reliability of the plating process by rapid recovery of a plating solution. CONSTITUTION: A plurality of plating baths are commonly connected with a plating solution tank by a pipe connection structure. Each plating bath includes a lower box(110), a supply pipe(120) of the plating solution, and a drain pipe(130) of the plating solution. The supply pipe(120) is centrally formed under a bottom surface of the lower box(110) and extended to the plating solution tank. The lower box(110) has two holes(112) formed in the bottom surface. The hole(112) is laterally longish and tapering downward. The drain pipe(130) branches out into two curved linkage pipes(140) and then connected to the respective holes(112). Since the plating bath is connected with the drain pipe(130) through the curved linkage pipes(140), fluid resistance is considerably reduced and therefore the plating solution gathered into the lower box(110) is rapidly recovered to the tank.
